This invention relates to ventilating windows or wind wings, such as are used in automotive vehicles and of the type wherein the wind wing is shiftable from closed position about an upright axis into different angular positions, and has for its object a-spring'tension device acting on the pivot pin when .the wind .wingis open into different angular positions to hold the wind wing in the angular position'and from closing under the force ofthe outer air or wind pressures against the same.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views. Y

Figure 1 is an enlargedfragmentary elevation of the wind wing and the contiguous portion of the window frame and the pivot pin, the friction holding or braking means, and the support therefor.

Figure 2 is a sectional view on line 2-2, Figure 1, looking to the left in Figure 1.

Figure 3 is an inverted plan view looking upwardly in Figure 1.

Figure 4 is a section on line 4-4, Figure 1.

This invention comprises means supported from the frame in which the pivoted window or wind wing is mounted to apply a friction braking force to the hinge or pivot pin of the wind wing against rotation, the braking means being adjustable to create suflicient friction to hold the wind wing in various open positions against closing under outside wind or air pressure. The friction means, in the illustrated embodiment, also constitutes a friction journal bearing for the pivot pin.

1 designates the window or wind wing sash, and 2 the window frame. Wind wings are mounted in openings in the car body, or in the doors, particularly the doors at the ends of the front seat. Owing to the streamlined contour of the car body, the wind wings are usually triangular in form and located in the front portions of the window openings. The window openings also enclose a glass pane, not shown, in the rear of the wind wing capable of being raised and lowered, the front edge of the glass pane abutting against the rear edge of the wind wing when the wing and glass pane are closed. The window frame 2 follows the contour of the opening in the door or car body.

3 designates the pivot or hinge pin which is 1 Claim. (01. 296-44) formed" with 'a bracket 4 secured to the lower,

rail of the sash of the wind wing, toward .-but spaced from the front end thereof so that when the rear-end of the wind wing-is-swung'ouh wardly, the front end in front of the axis of the pivot pinswings inward.

r 5 designates a bracket'in the formof a plate secured to the lower rail of the window frame 2 adjacent and at the rear of the pivot pin 3 and located in the planev of the pivot; pin of the frame 2 and s'ashyl, the plate havingzan angular flange 6 secured at 1 tothe bottom rail of the window frame 2, and also an angular flange 8 at its lower edge constituting a supportingr'shelf for thetensionspring to be presently" described. The bracket also formed witha projecting shoulder 9 between its upper and lower edges, which shoulder is opposed to the flange 8 and coactsawith*the upper edge of the tensionispringr- Theflange Band shoulder 9, together with a securing and clamping screw to be described, secures the spring to the bracket 5. The friction or brake means is thus supported from the window frame by the bracket.

The frame 2 is of conventional structure. It comprises a metal channel in which is seated a rubber finishing and weather strip Hi. The frame extends entirely around the window opening. The strip II] has a lip H overlying a metal finishing strip [2A secured to the upper edge wall I 2 of the window opening door or car body, in the usual way. The weather strip II is so formed as to permit the portion of the wind wing in front of the pivot pin 3 to swing inward, and the portion at the rear of the pivot to swing outwardly from closed position. The wind wing structures are rights and lefts. That here shown is for installation on the right hand side of the car body.

i4 designates the friction spring, this being in the form of a band l5 extending around the pivot pin and coacting with means thereon provided with a peripheral surface with which the inner face of the band coacts, the band having radially extending arms l6, l1, opposed to each other, the arms overlying the bracket 5 and one arm, as H, resting on the flange 8 at its lower edge and coacting with the shoulder 9 at its upper edge. The spring is secured to the bracket as by a clamping screw 18 extending through openings in the arms l6, l1, and threading into a hole at IS in the bracket 5, the screw serving not only to secure the spring to the bracket 5, but also to clamp the arms I6, [1, toward each other and thus apply the band IS with different pin 3. In order that the plug may be keyed to:

the pin 3 to rotate therewith, the pivot pin at its lower end is formed non-circular, as at- 23;

and the plug is formed with a complem'ental' non-circular axial opening Zfi-r The band fric tionally coacts with the pliig' 'anti provitleswa friction journal bearing for the pivot pin.

In assembling the wind wingain the frame; the pivot pin is passed through the opening in the frame 2, the plugencircled by the' ban'd' slipped axially over thelower end of the pin 3, andthm the spring secured to the bracket 5 'l n'r'means of thescr'ewflfll In 'order that the spring maybe: adjustedrelati'v'ely' to the axis 'of the pin- 3 oneof'thearms; as IT, ofthe spring' is formed with an enlarged perforation 25, and tl ie other' orout'er arm IS with; an elongatedi'slotifii ofr IBSS W-idth thanthe diameter of the h'eadiof thefscrew,i: the length of the slotand the diameter 'ofl'the hole beingsuch as toallbw the springiaband l 5"to be concentric witha' theaxist oi the :hingezpin .-3'; and the screw 18 to .b'e in; alinem'ent'with; thethreaded hole l'9' in the bracket fiz:
